BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a microwave oven, which isprovided on an external surface thereof with a saucer holder, and asaucer used with the microwave oven and removably engaged with thesaucer holder.

2. Description of the Related Art

As well known to those skilled in the art, a microwave oven is anappliance used to cook food laid in a cooking cavity thereof. To cookthe food, frictional heat is generated within the food as high-frequencyelectromagnetic waves cause molecules of moisture laden in the food tovibrate.

FIG. 1 is a perspective view of a conventional microwave oven. Referringto FIG. 1, the conventional microwave oven is provided at its front wallwith a door 100. A control panel 104 is provided on the front wall at aposition adjacent to the door 100. The door 100 is hinged to a body ofthe microwave oven, and allows a user to selectively open a cookingcavity 102. The control panel 104 occupies a smaller area in comparisonwith the door 100, and allows the user to input as well as confirmseveral cooking conditions, such as a cooking time and a cooked state offood.

A window 101 made of a transparent material is provided in the door 100in such a way as to cover a larger part of the door 100. When cookingfood using the above microwave oven, the user may view the cookingcavity 102 where food is cooked through the window 101 so the user mayconfirm the cooked state of the food. Recently, there has been effort toimprove the microwave oven such that the window 101 blockselectromagnetic waves due to the harmful effects of such waves on humanhealth. The control panel 104 is provided with control knobs 104 b and104 c to allow the user to input various conditions, including a desiredcooking time and a desired cooked state of food (for example, frozenfood), to a microprocessor in the microwave oven. The control panel 104also has a display 104 a. The display 104 a displays thereon severalvalues inputted by the user such as the cooking time. That is, thedisplay 104 a allows the user to confirm whether or not the valuesinputted using the control knobs 104 b and 104 c are correct, andwhether or not the cooking time has elapsed. The microwave oven is alsoprovided with a handle 103 used to open or close the door 100.

When it is desired to heat liquid food such as milk or water in themicrowave oven, the liquid food must be contained in a cup. Whenfinishing the cooking process, the liquid food is taken out from thecooking cavity 102 along with the cup. Typically, the cup as well as theliquid food contained in the cup are very hot. Thus, in order to carrythe heated cup, a saucer is required. Therefore, the conventionalmicrowave oven has a problem in that it is inconvenient and dangerous tocarry a cup containing liquid food heated and cooked in the microwaveoven.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to the present preferredembodiments of the present invention, examples of which are illustratedin the accompanying drawings, wherein like reference numerals refer tolike elements throughout.

FIGS. 2A, 2B, and 2C are front views showing a microwave oven providedon an external surface of a door of the microwave oven with saucerholders according to embodiments of the present invention. FIG. 3 is asectional view taken along a line A—A of FIG. 2A. FIG. 4A is aperspective view showing a projecting part of a saucer holder providedon the external surface of the microwave oven. FIGS. 4B and 4C areperspective views showing projecting parts of saucer holders.

As shown in FIG. 2A, the microwave oven includes a door 200 on a leftside of its front wall and a control panel 203 on a right side of thefront wall. The control panel 203 is used to input a desired cookingtime and a desired cooked state of food to be cooked in the microwaveoven. The door 200 is provided on its external surface with five saucerholders 201. Of the five saucer holders 201, three saucer holders 201are arranged on an upper portion of the door 200, while two saucerholders 201 are arranged on a lower portion of the door 200. A knob-typehandle 202 a is provided on the door 200 in such a way as to be alignedwith the two saucer holders 201 arranged on the lower portion of thedoor 200. Each of the saucer holders 201 includes a projecting part anda circular groove 201 b. The projecting part of each holder 201 includesa disc 201 a and a cylindrical sidewall 301 a (see FIG. 3). The disc 201a is positioned in parallel to the external surface of the door 200, andhas a predetermined diameter. The sidewall 301 a surrounds the disc 201a and perpendicularly extends from an edge of the disc 201 a. Further,the circular groove 201 b is formed around an outer circumference of theprojecting part to surround the projecting part, and has a predetermineddepth and width. Here, a saucer engages with the projecting part of thesaucer holder 201.

Preferably, the saucer holders 201 are made of a transparent material.In such a case, when the saucer is removed from the saucer holder 201, auser on an outside of the microwave oven may view the cooked state offood seated in a cooking cavity of the microwave oven through thetransparent saucer holder 201. Thus, the saucer holder 201 made of atransparent material serves as a window.

In FIG. 2B, the door 200 is provided with a window 11 which is made ofthe transparent material. Six saucer holders 201 are provided on thewindow 11. A grip-type handle 202 b is provided to a right side of thedoor 200 at a position outside the window 11. Since the saucer holders201 are made of the transparent material, the user may view the cookedstate of food in the microwave oven.

In FIG. 2C, the transparent window 11 is provided on a center portion ofthe door 200. Four saucer holders 201 are arranged around thetransparent window 11. Again, the saucer holders 201 are preferably madeof a transparent material.

FIG. 3 shows a cross-section taken along a line A—A of FIG. 2A. Thesidewall 301 a extends perpendicularly from the edge of the disc 201 a.

Preferably, a magnet or a magnetic material is provided on or at leaston a portion of one of the circular groove 201 b, the cylindricalsidewall 301 a, and the disc 201 a of the saucer holder 201. When eachsaucer is provided on its outer surface with a magnet or a magneticmaterial, the saucer is magnetically attached to the saucer holder 201having the magnet or the magnetic material.

FIG. 4A is an enlarged view of the projecting part of the saucer holder.Here, the saucer holder 201 is used with a saucer having an elasticrubber or silicone layer. That is, the saucer with such a rubber orsilicone layer removably engages with the projecting part of the saucerholder 201 through a frictional engagement.

In FIG. 4B, a helical thread 401 is exteriorly formed on the sidewall301 a of the projecting part. Alternatively, a helical groove may beformed on the sidewall 301 a in place of the helical thread 401. In thiscase, a helical groove or a helical thread is formed on the saucer tocorrespond to the helical thread or the helical groove of the saucerholder 201, such that the saucer engages with the saucer holder 201through a screw-type engagement. Thus, the helical groove and thread ofthe saucer and the saucer holder 201 are designed such that thescrew-type engagement of the saucer with the saucer holder 201 isaccomplished by rotating the saucer over the saucer holder 201 at asmall angle.

In FIG. 4C, the saucer is magnetically attached to the saucer holder201. The saucer holder 201 is provided at its sidewall 301 a with amagnet layer 33. Alternatively, a magnetic material layer may be used inplace of the magnet layer 33. Here, the saucer used with the saucerholder 201 is provided with a magnet layer or a magnetic material layerto correspond the magnetic material layer or the magnet layer 33 of thesaucer holder 201.

The feature of the structure of the saucer holder 201 and the saucerengaging with each other will be described in more detail with referenceto FIGS. 7A, 7B, and 7C. The saucer will be described below.

FIGS. 5A, 5B, 5C, 5D, and 5E are perspective views of the saucersdescribed above.

As shown in FIG. 5A, a saucer 500 a includes a seat 501 and acylindrical sidewall 502. A cup is seated on the seat 501 having a discshape. The sidewall 502 surrounds the seat 501 and perpendicularlyextends from an edge of the seat 501 to a predetermined height. Ahelical groove 504 is formed on an inner surface 503 of the sidewall502. A helical thread may be formed on the sidewall 502 in place of thehelical groove 504. Thus, the saucer holder 201 for the saucer 500 a isprovided with a helical thread or a helical groove to correspond to thesaucer 500 a such that the saucer 500 a engages with the saucer holder201 through the screw-type engagement. In such a case, the helicalgroove and thread are designed such that the screw-type engagement ofthe saucer 500 a with the saucer holder 201 is accomplished by rotatingthe saucer 500 a over the saucer holder 201 at a small angle.

In FIG. 5B, a saucer 500 b is provided on an inner surface 503 of itssidewall 502 with a silicone layer 603. The saucer 500 b elasticallyengages with the saucer holder 201 by an elastic force of the siliconelayer 603 of the sidewall 502. An elastic material layer such as arubber may be used instead of the silicone layer 603.

As shown in FIGS. 5C, 5D and 5E, a magnetic material layer or a magnetlayer is provided at a predetermined portion of a saucer 500 c, 500 d,or 500 e. In FIG. 5C, a magnetic layer 53 is provided on the innersurface of the sidewall 502. In FIG. 5D, a magnetic layer 63 having aring shape is provided along the edge of the sidewall 502. In FIG. 5E, athin magnetic layer 73 is provided on the outer surface of the seat 501.The saucers 500 c, 500 d, or 500 e are magnetically attached to thesaucer holder 201 provided with a magnetic material layer or a magnetlayer. The two saucers 500 d and 500 e of FIGS. 5D and 5E aremagnetically seated on the saucer holders 201. In addition, when theexternal surface of a body of the microwave oven is made of amagnetically attached material such as a steel sheet, the saucers 500 dand 500 e may be magnetically attached to the external surface of themicrowave oven.

Further, the saucers 500 a, 500 b, 500 c, 500 d, and 500 e are made of atransparent material such as glass and plastic. In such a case, thesaucer does not obstruct a user's field of vision, such that the useroutside the microwave oven may confirm the cooked state of food insidethe cooking cavity of the microwave oven.

FIG. 6 is a front view showing the microwave oven with the saucersengaged with the saucer holders provided on the microwave oven.
